MO]? MOLD FOR LIBRARY-E3TAK CONSTRUCTION.

Application filed September The object of this invention is to protect the enamel finish oi the shelves and supports of library stack constructions by providing a mold at the bottom of the construction so that the water used in mopping the floor splashes against the mold and not against the library construction.

Another object of the invention is to so construct this mop mold so that the water splashing against it will drain back onto the floor.

A further object of the invention is to so construct the mop mold so that it will prevent water from being splashed down onto the books supported on the library stack on the floor below. I

These and other objects of the invention will be fully illustrated in the drawing, de scribed in the specification and pointed out in the claims at the end thereof.

In the accompanying drawing:

Figure 1 is a vertical sectional view through a portion ofa multi-story library stack illustrating the new and improved mop mold.

Figure 2 is a detail perspective view of one end of the mop mold.

Figure 3 is a partial perspective and sec-v tional view of a portion of the mop mold and the library stack construction with which it is used.

In the several figures of the drawings like reference numerals indicate like parts.

The mop mold forming the subject matter of my present invention is especially adapted for use in connection with multi-story library stack constructions in which two or more stories are built one on top of the other, each being provided with a floor or platform in front of it. The mop molds are adapted to protect the finish of the library constructions at the bottom, that is, near the floor or platform, so that the water used in mopping the floor will not soil the finish of the library stacks. The mop molds are also intended to prevent the water used in mopping the floor from being splashed down onto the books in the stack on the floor below. It also allows the surface moisture splashed against the library stacks to drain back down onto the floor deck.

AS illustrated in the figures of the drawings, the mop mold is incorporated with the floor supporting construction which in the case illustrated among other parts consists 4, 1926. Serial No. 133,642.

of a suitable curb angle 1. The mop mold 2 attached to this curb angle by suitable screws 3, 3. The floor l: which may be of slate, glass or marble and is supported on the angle 1 with a suitable cement putty 5 interposed between the ends and bottoin oi? the slab. and the curb angle. As illustrated in section in Figures 1 and 3, the mop mold 2 has a vertical flange 6 which is the part of .he mold that is attached to the curb angle, and projects above the floor construction. The mold proJects rearwardly from this vertical nangeat a slight inclination to the horizontal. At the inner end of the mold another vertical flange but very much smaller, than the first one projects upwardly therefrom and extends to within a short distance of the bottom of the lower shelf of the library stack construction.

The ends of the mop mold that abut against the uprights 7 of the library stack construction are formed as illustrated in perspective in Figure 2. This supplemented by a vertical channel 8 that rests and is supported on the floor framing of the construction. The upright '7 extends into this vertical channel which proiects slightly above the mop mold as illustrated in Figures 1 and 2 while the ends of the mop mold embrace the outside of the vertical channel.

As illustrated in Figures 2 and 3 the vertical flange 6 of each of the mop molds extend to the middle or the vertical channel 8 which at this point extends the full height thereof and has a small horizontal flange 9 bent rearwardly therefrom to bridge the space between the flange 6 and the face of the vertical angle 8. A vertical flange 10 is also provided near each end and connects the vertical flange 6 with the rear of the mop mold.

As illustrated especially in Figure 1 wa ter from a mop or the mop itself will only come in contact with the mold 2 and will protect the finish of the lower portion oi the library stack construction so that it cannot get soiled by the mop. Water splashing up on the mop mold will quickly drain back over the inclined portion thereof and down onto the floor deck, and thus will be prevented from splashing into the stack construction or drop onto books supported in the stack below the floor that is being mopped.

Sufiicient space is left between the upper end of the mop mold. and the bottom 11 of the bottom shelf. This allows the air to circulate from the floor below to the floor above.

I claim:

1. A mop mold adapted, to be attached to a curb connecting a pair of uprights and comprising a lower upright section located in front of the pair of uprights. an upper upright section between the uprights with an inclined section projecting between the uprights connecting them, the lower section being adapted to be attached'to the curb and the i'niddle section being adapted to e::- tend rearwardly and up over the curb.

2. A mop mold adapted to be attached to a curb connecting a pair of uprights and comprising a lower upright section located in front of the pair of uprights, an upper upright section between the uprights with an inclined section projecting between the uprights connecting them, the lower section being adapted to be attached to the curb and the middle section being adapted to extend rearwardl and up over the curb, end sections extending lliHVilltllY from the lower uprigl'it section and the inclined section and forward from the upper section, said end sections being adapted to cover the front and sides of the u 'irights.

A mop mold adapted to be attached to a pair of uprights having a shelf supported between them and comprising a lower upright section, an upper upright section between the uprights with an inclined section projecting between the uprights con necting them, the lower section being adapted to be attached to the curb and the middle section beingadapted to extend rearwardl and up over the curb, with a space left open between the top of the mop mold and the bottom of the shelf to provide ventilation over and back of it.

at. In combination with a library stack construction having a pair of uprights and a shelf near the bottom thereof, of a mop mold. comprising" an upright fla lgc extending between said uprights, an inclined section projecting rearwardiy of said flange below said shelf, an upwardly projecting flange at the inner edge of said inclined section, said flange stopping short of the shelf to leave an opening between the Flange and the shelf forming a ventilating duct between said inclined section and the under side of said shelf.

5. A mop mold for a library stack construction having a pair of uprights with a shelf supported between them having a downwardly projecting flange at the front thereof, said mop mold comprising a vertical flange connecting the uprights at the front, an inclined flange projecting rear wardly from said vertical flange between the uprights, a vertical extension at the end of said rearwardly projecting extension with a space left open between said vertical extension and the downwardly projecting flange of said shelf to provide a ventilating opening between said mop mold and said shelf.

In testimony whereof I aiiix my signature.
